Slido.com is an audience interaction platform that lets people run live polls, Q&A sessions, quizzes, surveys, and feedback activities during meetings, classes, presentations, and events.
What can you actually do on Slido.com?
The main idea is simple because a presenter creates a Slido session while participants join from their own phones, tablets, or computers.
Participants can usually join through a QR code, direct link, or event code without installing an app.
Slido offers multiple-choice polls, word clouds, rating polls, open-text questions, rankings, quizzes, surveys, and live Q&A.
Audience members can also upvote questions, which helps popular questions move toward the top instead of forcing the host to choose questions randomly.
How popular is Slido?
Slido's About page says the platform has served more than 1.24 million customers, supported over 8 million interactive meetings, and engaged more than 240 million participants.
Those numbers make Slido much more than a small presentation add-on because it now operates at a scale used by businesses, schools, conference organizers, and distributed teams.
Its survey page also reports 28,200 surveys created in the previous month, which gives a useful picture of ongoing activity beyond live presentations.
Why is Slido useful during presentations?
A normal presentation sends information in one direction, while Slido gives the audience a simple way to respond while the presentation is still happening.
A trainer can test understanding with a quiz, a manager can measure employee sentiment with a poll, and a speaker can collect questions without stopping the presentation every few minutes.
This instant feedback can also expose confusion early because the presenter sees responses while there is still time to explain a difficult point.
Does Slido work with other presentation and meeting tools?
Slido integrates with PowerPoint, Google Slides, Webex, Microsoft Teams, and Zoom, according to its product information.
The PowerPoint and Google Slides integrations are especially useful because presenters can place interactive activities inside a normal slide deck instead of constantly switching browser windows.
Slido can also work alongside video conferencing platforms rather than replacing them because its main job is audience interaction instead of video calling.
What do you get with Slido for free?
The Basic plan currently allows up to 100 participants in one Slido session, according to answers published by Slido staff in its official community in 2026.
The free plan allows up to three polls and one quiz per Slido, while audience members can submit an unlimited number of Q&A questions within the participant limit.
Slido's homepage also advertises a forever-free Basic option and paid access starting from €15 per month, although prices and available plans can change by billing choice or region.
Anyone planning a paid event should therefore check the live Slido pricing page before budgeting.
How large can a Slido audience be?
Slido states that standard plans can support audiences ranging from 100 to 5,000 participants depending on the selected plan.
Organizations expecting more than 5,000 people can contact Slido about larger events rather than relying on a normal self-service plan.
This range makes the platform useful for anything from a small classroom to a large company-wide meeting, although organizers should match the plan to expected attendance before sharing the event link.
What happens to the results after a session?
Slido Analytics can show participation data, polling results, Q&A information, engagement metrics, and other session insights after an event.
Hosts can export more detailed information to formats and services such as Excel, Google Sheets, and PDF when supported by their plan.
Slido also provides Q&A sentiment analysis that uses an AI model to classify questions as positive, negative, or neutral, while allowing hosts to correct classifications they disagree with.
Who owns Slido today?
Slido began in Slovakia in 2012 and became part of Cisco after Cisco acquired the company in May 2021.
The acquisition explains Slido's close connection with Webex, although Slido continues to operate as a standalone audience interaction product as well.
Who should consider using Slido.com?
Slido.com makes the most sense for teachers, trainers, conference speakers, team leaders, webinar hosts, and organizations that want audience participation without forcing everyone to create another account or install another app.
Its strongest advantage is not simply polling because it combines live questions, voting, quizzes, surveys, presentation integrations, and post-event data inside one workflow.
For a small meeting, the free plan can be enough, while larger organizations should compare participant limits, moderation, analytics, privacy controls, exports, and enterprise features before choosing a paid plan.
